Example

using System;
using System.Collections;

namespace Samples
{
  public class HashtableSample
  {
    public static void Main()
    {
      Hashtable ht = new Hashtable();
      ht.Add(1, "damien");
      ht.Add(4, "maire");
      ht.Add(2, "mark");
      ht.Add(5, "sacha");
      ht.Add(3, "brad");
      ht.Add(6, "tamara");
      DisplayHashtable(ht);
    }
    public static void DisplayHashtable(Hashtable ht)
    {
      Console.WriteLine("Count: {0}", ht.Count );
      IDictionaryEnumerator de = ht.GetEnumerator();
      while(de.MoveNext())
        Console.WriteLine("Key: {0} :    Value: {1}",
                          de.Key,
                          de.Value);
    }
  }
}

The output is

Count: 6
Key: 6 :    Value: tamara
Key: 5 :    Value: sacha
Key: 4 :    Value: maire
Key: 3 :    Value: brad
Key: 2 :    Value: mark
Key: 1 :    Value: damien
